38 Under Windows, DLL (Dynamically-Linked Libraries) are generally used
39 to improve code modularity and sharing. A DLL can be loaded
40 automatically when the program is loaded (if it requires the DLL). The
41 program can also explicitly request Windows to load a DLL at any
42 moment during runtime, using the LoadLibrary function from the Win32
45 This naturally suggests to use DLLs as a plugin mechanism. For
46 instance, a web server could load extensions modules stored in DLLs at
47 runtime. But Windows does not really make it easy to implement plugins
48 that way. The reason is that when you try to create a DLL from a set
49 of object files, the linker needs to resolve all the symbols, which
50 leads to the very problem solved by FlexDLL:
52 Windows DLL cannot refer to symbols defined in the main application or
53 in previously loaded DLLs.
55 Some usual solutions exist, but they are not very flexible. A notable
56 exception is the edll library (its homepage also describes the usual
57 solutions), which follows a rather drastic approach; indeed, edll
58 implements a new dynamic linker which can directly load object files
59 (without creating a Windows DLL).
61 FlexDLL is another solution to the same problem. Contrary to edll, it
62 relies on the native static and dynamic linkers. Also, it works both
63 with the Microsoft environment (MS linker, Visual Studio compilers)
64 and with Cygwin (GNU linker and compilers, in Cygwin or MinGW
65 mode). Actually, FlexDLL implements mostly the usual dlopen POSIX API,
66 without trying to be fully conformant though (e.g. it does not respect
67 the official priority ordering for symbol resolution). This should
68 make it easy to port applications developed for Unix.
